Solution Overview

Problem

Existing tools and procedures for knee osteotomies lack accuracy and precision in correcting the alignment of the knee joint, which limits the effectiveness of the procedure.

Innovation Solution

A surgical guide assembly is provided, comprising a body that secures to the tibia bone and multiple guide modules, including drilling, cutting, anchor, predrilling, and spreader modules, which guide surgical tools to ensure precise alignment and execution of osteotomy procedures, with modules being removably attachable and customizable to patient anatomy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If existing tools and procedures are used for knee osteotomy, then the procedure can be performed, but the accuracy and precision of knee alignment correction is insufficient

Engineering Contradiction:

Improveaccuracy of knee alignment correctionVSAvoidprecision of cut and hole formation

Core Design Contradiction:

Measurement precisionVSManufacturing precision

Solution Approach 1:

The surgical guide assembly is divided into multiple detachable guide modules, each designed for specific surgical tasks (drilling, cutting, spreading). This segmentation allows each module to be optimized for its specific function, improving overall precision while maintaining operational flexibility.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The surgical guide assembly acts as an intermediary device between the surgeon and the bone, providing precise geometric references and constraints. The guide modules translate surgical plans into accurate physical actions through predefined drill guides, cut guides, and spreader guides, ensuring high measurement and manufacturing precision.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If a fixed surgical guide design is used, then the device structure is simple, but it cannot be adapted to different patient anatomies and surgical requirements

Engineering Contradiction:

Improveadaptability to patient anatomyVSAvoidcomplexity of guide assembly structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The guide assembly is segmented into multiple detachable modules that can be selectively attached and configured. Each module serves a specific surgical function and can be removed or replaced based on the patient's anatomy and surgical needs, providing adaptability without requiring complete redesign for each case.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The guide assembly transitions from a static, fixed design to a dynamic, reconfigurable system. Modules can be attached, detached, and repositioned during surgery to adapt to different anatomical variations and surgical requirements, making the system versatile while maintaining manageable complexity through standardized interfaces.

Inventive Principle:

Principle #15Dynamics
